Description

Technical Field

[0001] This utility model relates to the field of rotating drums in biopharmaceutical manufacturing, and in particular to a liquid-cooled rotating drum. Background Technology

[0002] Currently, biological dressings are needed to protect the wound in burn treatment. Among these biological dressings are those made from pigskin (decellularized dermal matrix dressings). Pigskin dressings require rinsing and degreasing processes, which necessitate processing the raw materials in a rotating drum. During this process, the machine itself generates heat, and the friction between the tumbling raw materials also generates heat. The cleaning and degreasing processes must be carried out at low temperatures. If the temperature is too high (above 30 degrees Celsius) or the time is too long, the pigskin will begin to undergo physical changes, and the internal collagen will dissolve. The original solution involved multiple cleaning and degreasing processes to control the time the pigskin spends in the rotating drum, preventing excessively high temperatures. However, this process is inefficient and increases the workload for workers. Utility Model Content

The drive device is fixedly installed inside the base. The drum also includes an outer tub, an inner tub, and a drive shaft. The inner tub is located inside the outer tub and is connected to the drive device via the drive shaft. The outer tub is a fixed tub and is fixedly connected to the base. A spray pipe is provided at the top of the outer tub, and a drain pipe is provided at the bottom. Watertight doors are provided on the same side of both the outer tub and the inner tub.

[0004] The spray pipe includes a distribution pipe and several branch pipes, which are arranged on both sides of the distribution pipe in a figure-eight pattern.

[0005] The outer barrel is connected to the drive shaft by a rubber sealing ring, and a collection groove is provided on the outer barrel at the position corresponding to the drive shaft.

[0006] The inner wall of the inner barrel is evenly provided with several lifting ribs.

[0007] The outer wall of the outer barrel is provided with heat-insulating sponge.

[0008] The inner and outer barrels are each equipped with an observation window.

[0009] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: By adopting the above technical solution, this utility model has the following technical effects: It can clean and degrease pigskin raw materials for a long time. The temperature of the inner barrel is controlled by spraying to prevent it from rising. The branch pipes spray the inner barrel to both sides, which can cool the entire inner barrel more evenly. It has a simple structure, is reliable and safe, and can effectively reduce the labor intensity of workers. Attached Figure Description

[0011] All features disclosed in this specification, or steps in all methods or processes disclosed herein, may be combined in any way, except for mutually exclusive features and / or steps.

[0012] Any feature disclosed in this specification, unless otherwise stated, may be replaced by other equivalent or similar features. That is, unless otherwise stated, each feature is merely one example of a series of equivalent or similar features.

[0013] like Figure 1 The liquid-cooled drum shown includes a drive unit 2 and a base 1. The drive unit 2 is fixedly installed inside the base 1. It also includes an outer barrel 3, an inner barrel 4, and a drive shaft 5. The inner barrel 4 is installed inside the outer barrel 3 and is connected to the drive unit 2 through the drive shaft 5. The other end of the inner barrel 4 is connected to the outer barrel 3 through a bearing. The outer barrel 3 is a fixed barrel and is fixedly connected to the base 1. A spray pipe 6 is provided at the top of the outer barrel 3 and a drain pipe 7 is provided at the bottom. Watertight doors 8 are provided on the same side of the outer barrel 3 and the inner barrel 4 respectively. The watertight door 8 includes clamps and sealing plates on both sides. One end of the clamp is fixed to the barrel body, and the other end is fixed to the barrel body eccentrically through an eccentric handle. The sealing plate has a perforated plate above it and no perforated plate below it. A sealing strip is provided at the contact position between the no-perforated plate and the barrel body.

[0014] The spray pipe 6 includes a distribution pipe 6.1 and several branch pipes 6.2, which are arranged on both sides of the distribution pipe 6.1 in a figure-eight pattern.

[0015] The outer tub 3 is connected to the drive shaft 5 by a rubber sealing ring. A collection trough 9 is provided on the outer tub 3 at the position corresponding to the drive shaft 5. A drain pipe 7 is provided at the bottom of the collection trough 9. The outer tub 3 and the drive shaft 5 are dynamically sealed. A small amount of leakage will occur when the spray water volume is large. The water collected in the collection trough 9 flows into the drain pipe 7.

[0016] The inner wall of the inner barrel 4 is evenly provided with a number of lifting ribs 4.1. The material can be lifted by the lifting ribs 4.1 and washed by gravity, thereby improving the washing efficiency.

[0017] The outer wall of the outer barrel 3 is provided with heat-insulating sponge to keep the outer barrel 3 warm and maintain the low temperature inside the barrel.

[0018] The inner tub 4 and the outer tub 3 are each provided with an observation window 10.

[0019] The drain pipe 7 is equipped with a three-way valve, which is connected to a return water pipe and a sewage pipe. It can switch between sewage discharge or return water cooling and then pumping it back into the spray pipe.

[0020] During operation: Rotate the inner tub 4 to align the watertight door of the inner tub 4 with the watertight door of the outer tub 3, and open it. Place the raw material (pigskin) into the inner tub 4, add cleaning agent or degreasing agent, add an appropriate amount of water, close the watertight door, and turn on the switch. The drive device 2 drives the inner tub 4 to rotate via the transmission shaft 5, and the spray pipe 6 operates. The distribution pipe 6.1 distributes water to the branch pipes 6.2 to spray the inner tub 4. The branch pipes 6.2 are located on both sides of the center line of the inner tub to ensure that the entire tub is sprayed with cooling water. The cooling water removes heat and flows out from the drain pipe at the bottom of the outer tub 3. 7. The circulating water enters the external circulation pump, which can be connected to a cold water tank or condenser to cool the circulating water. The cooled water is then sprayed onto the inner tank 4 again through the spray pipe to cool it down. After production is completed, the watertight door 8 of the outer tank is opened, and the watertight door 8 of the inner tank is switched to the orifice plate position to release the wastewater from cleaning the materials. The tee on the drain pipe 7 is switched to the sewage pipe in advance for sewage discharge. After sewage discharge is completed, the watertight door of the inner tank 4 is fully opened for material feeding. The entire operation is complete. During the process, the outer tank 3 can be empty or half full of water to cool the inner tank 4.

[0021] It can clean and degrease pigskin raw materials for a long time, and the temperature of the inner barrel is controlled by spraying to prevent it from rising. It has a simple structure, is reliable and safe, and can effectively reduce the labor intensity of workers.
